Microfibrillar composites (MFCs) from recycled high density polyethylene (R-HDPE)/recycled poly (ethylene terephthalate) (R-PET) (75/25 w/w) were made through reactive extrusion and post-extrusion strand stretching. The resultant MFCs could be processed at HDPE processing temperature. The compatibility between microfibers and R-HDPE matrix was improved through compatibilizers. Of the three comp...

In recent years, the development and use of polymeric nanocomposites in creating advanced materials has expanded exponentially. A substantial amount of research has been done in order to design polymeric nanocomposites in a safe and efficient manner. In the present study, the impact of processing parameters, such as, barrel temperature, and residence time on the mechanical and thermal propertie...

The automated separation of plastic waste fractions intended for mechanical recycling is associated with substantial investments. It is therefore essential to evaluate to what degree separation really brings value to waste plastics as raw materials for new products. The possibility of reducing separation requirements and broadening the range of possible applications for recycled materials throu...

The effect of substrate interferences from high-density polyethylene (HDPE) on the ability to associate an ignitable liquid residue with the corresponding liquid standard, using statistical procedures, is demonstrated. Gasoline, kerosene, and lighter fluid, at three different evaporation levels, were spiked onto HDPE and subsequently burned to generate simulated ignitable liquid residues (ILRs)...

There is growing interest in sustainable road pavement technologies to protect the environment and provide economic benefits. Post-consumer recycled (PCR) plastics are considered for construction address threat of plastic waste materials (PWM) improve sustainability. Asphalt highly PWM recycling due its large daily production. The purpose this study investigate performance asphalt mixture conta...

The volume of municipal solid waste in developing countries continues to grow, yet disposal and management have become significant challenges. As a result, proper strategy is required. feasibility making paver blocks from plastic for construction work was investigated this study. Paver manufactured (PP HDPE) sand varied proportions were evaluated compressive strength, water absorption, abrasion...

The inert and oxidative flash pyrolysis of High Density Poly-Ethylene (HDPE) is studied 6 up to 20 000 K.s, under pressure up to 3.0 MPa and at temperature ranging from 1000 K to 7 1500 K. These conditions are considered to represent those waited onboard a hybrid rocket 8 engine using HDPE as solid fuel. Recycling applications may also find some interest. The 9 pyrolysis products are quantified...

High-density polyethylene (HDPE) melts have been previously identified as having an unusually high degree of molecular order, but the rheological implications of this have heretofore not been explored. This has been a serious oversight, inasmuch as HDPE melt processing is one of the major tasks of the world's polymer industry. Here, we investigate several industrial samples of HDPE, covering a ...

The fiber characteristics (i.e., the fiber type, morphology, and dimension) and polymer melt flow index (MFI) significantly affected mechanical properties of sugarcane fiber/HDPE composites. The length and diameter of sugarcane fibers followed a lognormal distribution before and after compounding. The long fibers had a significant reduction in the dimension and aspect ratio during compounding. ...

Using laboratory soil chambers a nonscaled representation of an agricultural raised bed was constructed. For a sandy loam soil, 1,3-dichloropropene (1,3-D) and chloropicrin (CP) were applied at 5 cm depth with an excess of water (simulated drip irrigation). Application was made under both high density polyethylene (HDPE) and virtually impermeable film (VIF) covering the soil bed (the furrow was...
